Tundra Upgrade Advice

Hey folks! I'm look for a little input before I take on the Tundra brake upgrade. I've done a ton of research and read through all the great threads on this topic, but just have a few questions before pulling the trigger on parts and getting to work.

I am looking at a set of Callahan 13WLs that come with rotors and pads on eBay. I have a 2001, so from what I've read there should be any problems fitting my stock wheels (16s) over the 231mm calipers. Can anyone confirm this from experience? Does anyone have experience with the Callahan parts? I've heard they are the same company as Powerstop just branded as Callahan.

My main question is about bleeding. I want to do an entire fluid flush, and I was hoping to use speed bleeders. I'm just not sure what order to do all of this in. I want to flush the system through the old calipers so I don't get any old fluid in the new ones, but I also would rather not install speed bleeders on the old calipers and then move them to the new ones. It may not be a valid concern, but my thought is that changing speed bleeders from one caliper to the next wouldn't be recommended because of the loctite or whatever they use on the threads. Any suggestions as to the best possible way/order in which to do the brake upgrade and fluid flush would be GREATLY appreciated!

My final concern is about the condition of the rear brakes. I have yet to inspect them, but they are original, I'm at about 200K, and I think they may be out of adjustment (possibly contributing to the reason I seem to have gone through pads and rotors so quickly in the past). I still have much research to do on here about how to inspect, adjust, and replace rear brake parts, but my question is this. If I find that my rear brake are in need of some service (beyond adjustment), would there be any catastrophic effect on my new front brakes if I were to put off the rear brake service until spring? or would it just wear a little faster? I'm out here in Chicago and I have no garage, so it's hard for me to find a warm space to work in this time of year. So between that and my wallet, I'd rather not to both front and rear at once.

Ok one more...how important is the exact torquing of the caliper bolts and brake lines?

I would really appreciate any advice. You guys are awesome. Thanks!

Not all stock 16 inch rims fit over 231mm calipers. Provide a picture of what rims you have and we can tell you if they will work.

If I were you, I'd just bleed the brakes the traditional way with a buddy helping you with pumping and holding the brakes while you're under the rig opening the stock bleeders. Follow the video below for the proper sequence. Since you have a 2001, you'll want to have the ignition key in the "On" position.

Even at 200k, your rear brake shoes might still have a lot of meat on them. If you use your parking brake on a regular basis, the auto adjusters should be keeping the shoes properly adjusted. If you find the shoes are worn down pretty far, buy an OEM set of shoes and do the work yourself. It's not hard.

Torque the caliper bolts to 90 ft-lbf. For the brake line flare nut fittings, just get them tight unless you happen to have special flare nut crows foot wrenches that can attach to your torque wrench.

If Tommy Boy and Richard are still slinging those Callahan brake parts, I may tell ya to pass on them.

In reality they are probably just fine but consider painting them so they don't rust up in the Illinois winters.

I was thinking the same damn thing when I read the name Callahan. Tommy Boy is a good movie.

They come painted red. Installed mine 2 weeks ago. Work great. Brakes are excellent. I highly recommend them. $324 for calipers, rotors, and pads. Can't go wrong.

got a link? This is my next upgrade. Did you use your stock dust shield or get a tundra shield?
 
My aftermarket Tundra calipers from Napa are trash. I would rather run some used oem calipers off ebay with new oem rotors, pads and shims.

Here's the wheel on my '01.

Thanks for all the advice! What I wouldn't give to buy a set of brake pads from Chris Farley

What don’t you like about your Napa calipers? I’m running them with OEM everything else and haven’t had any problems.
 
They are starting to stick. Uneven pad wear. I think I'm going to find some oems and rebuild them.

Don't the NAPA calipers have a lifetime warranty? Why not just try swapping them out? Maybe you got one that's wonky.

I put NAPA remans on my 4th gen and they were awesome.

I think they do but can't find receipt. Napa does not keep computer records.

Cardone makes them for napa so they are not the best.

They worked fine for about a year at most.
 
One more question - I plan to flush the whole system before changing out the calipers to keep the new ones clean as possible. After install the calipers, do I need to bleed @ all 4 wheels again or just the front two that I am working on?
